Collection of various types

Question

In the current system I'm working on I need to have functionality for ammendments.

That being that a user can create an ammendment package and that package contains new version of various domain objects (not structure changes just data changes).

I want to have an "AmmendmentPackage" that contains all of the ammendments that are to be made to various different types of elements.

So far I have

 public class AmmendmentPackage : BaseObject
 {
    public string Name {get;set;}

    public string Description { get; set; }

    public int MajorVersionNumber { get; set; }

    public int MinorVersionNumber { get; set; }

    public bool IsGazetted { get; set; }

    public AmmendmentPackageState State { get; set; }
}

public class Ammendment<T>
{
    public T AmmendedElement{get;set;}

    public AmmendmentState State {get;set;}

    public ConcurrencyDetails ConcurrencyState { get; set; }
}

How do I go about having the AmmendmentPackage contain number of different Ammentments of various types. I was thinking about using ICollection but then I would have an ICollection<Ammenndment<T>> and I could only have one type of ammendment in the package.

Also was considering using a dictionary but not 100% sure how I would work that in just yet, hopefully I haven't missed something really basic but would appreciate some ideas.

Cheers

This is not possible.
You cannot have a strongly-typed collection that holds different types of objects.

Instead, you should make a non-generic base class or interface and make a collection of those.
